Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991562, here are decompositions:

31 + 991531 = 991562
79 + 991483 = 991562
109 + 991453 = 991562
181 + 991381 = 991562
433 + 991129 = 991562
499 + 991063 = 991562
601 + 990961 = 991562
673 + 990889 = 991562

Showing the first eight; more decompositions exist.
